VM Manager does not remember its restored window size

[robpats]

If the window of VM Manager has been maximized and then restored, VM Manager does not remember its restored window size between restarts. VirtualBox.xml stores the bounds of maximized window instead of the restored window in ExtraDataItem "GUI/LastWindowPosition".

I don't know whether it is a related issue or not. When I try to reproduce this issue, a crash occurred immediately after restarting VM Manager. VM Manager is shown in maximized windows size (but the window is not maximized) before crash. I can't reproduce this crash again and find any memory dumps of this crash.

This bug is also reproducible in VirtualBox 5.2.22.
